After a year of solid and stable performance, my n810 is in constant need of screen recalibration. Reloading firmware doesn't help and so look to be hardware related... I've sent it out to the "Nokia Repair Cntr" and received a Palco quote to repair for $108 USD. For that cost, does it make sense to repair, or just purchase a new one and sell the old one on eBay? TIA
